Back to original post.IMO the power between the two isn't worth the cost.If you want more than standard 406,which can be pretty strong,then add a small nitrous system.Heck a 300 dollars sytem will give you more power then the extra 28 ci will.Plus you only pay when you use it.A basic plate system will give you 75 to 200 hp.Just do few extras doing your buld and your good to go.Forged pistons and good rings.Maybe a ignition control system that will retard timing at the hit of the button.I normally retard 2 degrees per 50 or 75 hp,at 200 I would go 6 to 8 degrees retard.Might be little much but its safer to remove to much then to little.
Don't worry abpout the night mares you hear about nitrous its basically from those who don't install proper safety switches or maintance there stuff like they should.
